Does requestImageDataAndOrientationForAsset always send JPEG data?

Dear Experts,

When I use PHImageManager's requestImageDataAndOrientationForAsset method I always seem to get JPEG data, even when the original items in the photo library are PNGs (such as screenshots) or HEICs.

Have I missed a setting somewhere that determines whether or not a "most compatible" format is used in this API?

Thanks.
